Have you ever thought about what QR Codes and Barcodes are? Whether for payment on your phone or when buying groceries, you’ve undoubtedly scanned both at some point.
So, what separates these two? And above all, why is this relevant to you?
This post will clearly explain the primary distinctions between both: barcode vs QR Code.
Let’s get started and see which is better for your business.
A. Let’s understand: Barcode and QR Code difference
Let’s get things straight. Barcodes and QR Codes are commonplace. Products, signage, and documents have those designs in black and white. But what are they, and why is it vital that you know?
Barcodes are the old-school champions. They have existed since the 1970s. Barcodes consist of lines and spaces and aid retailers in inventory control.
The barcode on your purchase is scanned by the cashier, who uses it to notify the computer what you are purchasing.
Though they have limitations (more on that in subsequent sections), barcodes are fantastic for speedy sales. They merely store a product number and other small amounts of data.
Let’s now discuss QR Codes. These have far greater power than barcodes. Numerous pieces of data, including contact details, internet links, and even films, can be stored in a QR Code.
Simply use your smartphone to scan it, and you’ll instantly be able to access anything within.
These days, QR Codes can be found in advertisements and restaurant menus. They facilitate the quick connection between the physical and digital worlds.
| Feature | QR Codes | Barcodes |
| Structure | Square, made up of dots and squares | Long, rectangular, parallel lines with different widths |
| Data Capacity | Up to 7,000 numeric characters or 4,000 alphanumeric characters | 1D barcodes: 20–25 characters; 2D barcodes (like PDF417): up to 1,800 |
| Error Correction | Built-in error correction can be scanned if partially damaged | There is little to no error correction; scanning fails if the barcode is slightly damaged |
| Scanning Equipment | All the smartphone cameras, QR Code scanners | Barcode scanners and some smartphones for 2D codes |
| Typical use cases | Payments, advertising, event tickets, marketing, inventory and logistics, business cards, product packaging, restaurants, etc. | Retail, product identification, inventory control, shipping |
| Cost & Implementation | Generally low-cost, easy to implement | Cost-effective for small data; 2D barcodes require more advanced tech |
| Scan Speed | Fast, omnidirectional scanning | Slower, unidirectional scanning for 1D; 2D is faster but less common |
| Security Features | Can be encrypted, secure data transmission possible | Low security, basic identification purpose |

| Error Rates | Low error rates due to error correction | Higher error rates if damaged or dirty |
| Versatility | Highly versatile, used across many industries | Less versatile, mainly used for inventory and retail purposes |
B. A look back: The evolution of barcodes and QR Codes
Let’s travel down memory lane and discover the stories behind barcodes and QR Codes.
The introduction of barcodes into the retail market in the 1970s dramatically transformed it. The first scan was of a pack of Wrigley’s chewing gum and was regarded as the dawn of a new age in inventory control.
These plain black lines and white space helped the shops reduce checkouts drastically.
It also minimized human error by streamlining inventory management. Retailers have widely used this for several decades.
Revolutionary technology, the QR Code, appeared in the 1990s. Initially developed in Japan for the automobile sector, it soon became prominent.
It could store a much more significant amount of data than traditional barcodes.
Users could quickly scan the barcode to retrieve product data, promotional offers, and URLs.
QRs gained immense appeal in the 2010s as smartphones became more and more commonplace.
Barcodes and QR Codes are part of our daily lives now. Let us now learn more about them.
C. Visual differences: How to spot a barcode vs QR Code
When examining a product, have you ever noticed that you can’t tell if the code is a QR or a barcode?
Despite their initial similarity, these two codes have distinguishing characteristics. With the proper knowledge, make it simple to differentiate between them.
Usually consisting of several parallel lines with different widths, barcodes are long and rectangular.
Their purpose is to be read by laser scanners, and typically, they hold a series of digits that link to particular products.
Conversely, QR Codes have a square form and are covered in an intricate design of dots and squares made of black.
QR Codes are far more capable of storing information than barcodes, including text, video, and URL links.
By aiming their camera at the code, customers can rapidly access a plethora of information thanks to its quick scanning design, which works with smartphones.
The first patent for barcode technology was issued to Norman Joseph Woodland and Bernard Silver in 1952.
D. Data capacity: How much information can they hold
While both barcodes and QR Codes can be used to store data, their data structures and capacities differ. Let us see how:
1. Types of barcodes
a. 1D Barcodes
1D or linear barcodes consist of vertical lines of varying widths and spacing. Examples include UPC (Universal Product Code) and EAN (European Article Number). These barcodes are widely used in retail for product identification and inventory management.
Data Capacity: 1D barcodes typically store up to 20–25 characters. Since they are encoded in a linear format, their data capacity is limited compared to 2D codes.
b. 2D Barcodes
2D barcodes encode data horizontally and vertically, allowing for more data storage. One well-known example is the PDF417 barcode used in shipping and identification cards.
Data Capacity: 2D barcodes, like PDF417, can store up to 1,800 characters. While this is a significant improvement over 1D barcodes, QR Codes still need to be more widely used.
2. QR Codes: Structure and capacity
a. QR Code structure
QR Codes are square-shaped, scannable from multiple angles, and can store much more data than traditional barcodes. They are highly versatile and commonly used in mobile apps, digital payments, and website links.
b. Data capacity
QR Codes can store large amounts of information, including:
– Up to 7,000 numeric characters
– Up to 4,000 alphanumeric characters
– Kanji characters and binary data
There are 40 different QR Code versions, varying capacities depending on the error correction level (L, M, Q, H) chosen.
c. Error correction
One of the critical features of QR Codes is their built-in error correction. Even if part of the code is damaged or obscured, it can still be accurately scanned, making it a reliable option in many industries.
3. Use cases
